Laboratory reagent grade, sterile distilled water for your laboratory needs. This water is purified by steam distillation and sterile filtered for use as a research laboratory reagent. The distilled water is low endotoxin <0.025EU/ml and low conductivity (<10uS). This water is ideal for the preparation of reagents, rinsing of glassware and plasticware, and various other laboratory and research applications. No toxic agents such as DEPC are included in the preparation of distilled water, eliminating interference with enzymatic analysis.

The Gram staining method was first described in 1844 by the Danish bacteriologist Hans Christian Gram, after whom the test was named. The Gram staining test for bacteria is one of the most important tests in microbiology and is often one of the first tests performed in the identification of bacteria. The Gram staining method utilises the properties of bacterial cell walls and the stain crystal violet. Gram-positive microorganisms have a higher peptidoglycan and lower lipid content than Gram-negative bacteria in their cell walls and this makes them capable of retaining the Gram stain. This kit is supplied with two strains of bacteria and all the necessary components to carry out the Gram staining.

HOOK™ IgG biotinylation kits are designed for the biotinylation of IgG molecules by immobilising the IgG molecules on a solid support. Nickel chelating resin allows for the rapid removal of uncoupled biotin and therefore eliminates the need for further dialysis or desalting of the biotinylated antibody.

Detergents are essential for protein solubility during protein extraction and sample preparation, especially when working with hydrophobic proteins. The presence of high concentrations of detergents in protein samples can impair ELISA, IEF, protease digestion of proteins and suppress peptide ionisation when analysed by mass spectrometry.

Supplier: G-Biosciences

Ion exchange chromatography is used to separate charged molecules from complex biological samples. The charged molecules bind to a solid support carrying an opposite charge to the molecule. Proteins contain regions of charged groups on the surface which interact with the ion exchange groups immobilised on the solid support (resin column). Immobilised proteins are eluted by changing either pH or the salt gradient or a combination of both. This lab activity involves preparation of a crude protein extract and running ion exchange chromatography for isolation of proteins.

The femtoELISA™ kits utilise a non animal protein blocker, NAP-BLOCKER™ that minimises cross-reactivity with researcher's antigens and antibodies. For the detection of HRP, an improved, ultra sensitive, non volatile, stable colorimetric substrate based on tetramethyl benzidine (TMB) is supplied. Reagent does not require hydrogen peroxide that can have detrimental effects on many biological factors, which may ultimately affect the assays.
